我只能创建一个DateTimeFormatter的静态实例吗

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class DateTimeExample {
    public static void main(String[] args) {
        DateTimeFormatter formatter1 = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        DateTimeFormatter formatter2 = DateTimeFormatter.ofPattern("dd/MM/yyyy");

        LocalDateTime dateTime = LocalDateTime.now();

        String formattedDateTime1 = dateTime.format(formatter1);
        String formattedDateTime2 = dateTime.format(formatter2);

        System.out.println("Formatted DateTime 1: " + formattedDateTime1);
        System.out.println("Formatted DateTime 2: " + formattedDateTime2);
    }
}
